Is the 300 blackout my solution? Looks like cheaper ammo is in the pipeline, and the only thing that I don't like about the AR is the cartridge that it's chambered for. I just can't bring myself to get an AK or mini 30, and seems like the 300 aac is the 7.62 for the AR world (I know about the problems feeding real 7.62x39 in a stock AR). Wanna kill these ads? We can help!
